OIL-BURNER FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 554,435, dated February11, 1896.

Application filed October 22, 1895. Serial No. 566,461. (No model.)

To all whom, it may concern.:

Be it known that I, WILLIAM BOOTH, a citizen of the United States,residing at Los Angoles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Improvement in Oil-Burnersfor Locomotives, of which the following is a speciiication.

My invention relates particularly to an improvement upon an apparatusfor burning petroleum in furnaces, fully described lin Letters Patentissued to me February 5, 1895,

the steam, all so arranged that the oil will drip or flow upon the sheetof steam issuing from the steam-slit, and thus be atomized and driveninto the iirebox in a manner suitable to insure perfect combustion. Ihave found in practice that with this construction the intense heat towhich the end of the burner is subjected almost invariably causes thecentral portion of the cap, or that portion. which forms the divisionbetween the oil and steam chambers, to spring or warp, thus causing thejoint to open and allowing the oil to pass downward into the steamchamber. The steam-slit is very narrow, and is only de signed for thepassage therethrough of the steam necessary to atomize the oil. The consequence is that when the oil enters the steam chamber, and isdischarged with the steam through the steam-slit a sufficient quantityof oil and steam cannot be forced through the slit to produce the amountof heat for which the burner is designed, thus causing considerabledifliculty and annoyance. l

The object of my present invention is to so construct and arrange myburner that all danger of accidental escape of the oil into thesteam-chamber will be avoided.

The accompanying drawings illustrate my invention.

Figure lis alongitudinalmid-section of my improved burner with all theparts in position. Fig. 2 is a perspective view of my improved burnerwith the cap removed from the end of the lower wall of thesteam-chamber. Fig. 3 is afront elevation of the burner.

In the drawings, A represents the burner which is rectangular in shape,and is ordinarily made of cast-metal. This is provided with twolongitudinal passages B and C, as described in my former patent,excepting that the casting is made long enough to form the outer end ofthe chamber B instead of such outer end being formed by a removable cap.By making the partition A" integral there is no joint to become sprungso as to leak. 'Io prevent the oil from spreading unduly upon the( endof the burner, I cast a lip C upon the end of the burner and arrange itI partially surrounding the oil-outlet c.

The lower wall A of the burner terminates at a distance from the extremeouter end of the casting, and I complete the steam-chamber by means of abar or cap D which I se- 'cure to the burner by set-screws E, the capbeing so arranged as to form, in combination with the lower face of theintegral partition A of the burner, a steam-slit F through. which thesteam discharges. .By this means I entirely avoid all liability of theoil feeding into thesteam-ehamber, and am enabled to produce a burnerwhich will always produce the amount of heat which it is designed toproduce. y

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The burner set forth consisting of a casing having an integral partitionarranged to di vide the interior oi' the casing into two parallellongitudinal passages or chambers, one wall of one of the chambersterminating at a distance from the end of the burner, and abar orcap-piece secured to the burner to form the continuation of such walland to complete the other chamber, such chamber terminating in a slitfor the passage of the steam.

WILLIAM BOOTH.
